Application filed October 28, 1919. Serial No. 334,014.

To all whom it may concern:

Be it known that I ENNIS NEVINS, a citizen of .the United tates,residing at El Paso, in the county of El Paso and State of Texas, haveinvented new and useful Im provements in Quantity Regulators, of whichthe following is a specification.

This invention relates to regulators especially adapted for controllingthe passage of a conduitor pipe and aims to provide means whereby theflow through said conduit or pipe, will be automatically regulated bythe fluid passing therethrough, so that after the regulatorhas been setfor the passage of a predetermined quantity 1 of fluld, the flow throu hthe conduit will be uniformly maintainec I Another object of theinvention is the provision of a device of this character, which isexceedingly simple of construction and effi-,'

cient in operation.

Other objects and advantages of the in-' vention will appear as thefollowing descrip: tion is read in connection with the accompanyingdrawings, in which the figure shown is a sectional view through aregulator embodying the present invention.

Referring to the drawings in detail,

wherein like characters of reference denote corresponding parts, thereis illustrated at 10, a conduit or pipe, for the purpose of conveyingair or other fluid from one point to another.

Located upon the outside of the conduit or pipe, are a pair of closedvessels or containers 11, the said vessels being spaced apart andconnected by means of a pipe 12, which communicates with each of thecontainers. The pipe 12 is pivotally mounted, as shown at 13, upon asuitable support 13, which may rest upon the conduit 10, or upon anyother suitable support.

One of the containers 11 communicates with one end of a flexible tube14, at a point near its top, the opposite end of the said. tube beingconnected to and communieating with a static pressure pipe 15, whichpipe in turn communicates with the interior of the pipe. The othercontainer 11 communicates with a tube 16, through the medium of aflexible tube 17 the tube 16 extending within the conduit 10 and beingprovided with an open end 18.

Located within the conduit 10, is a valve 19, which is pivotallymounted, as shown at passage through the conduit.

-si te end pivoted to the 20, to provide a throttle for controlling theThis valve is provided with an arm 21, whose end is pivotally connectedto one end of a lever 22, the opposite end of this lever being pivotedto the .pipe 12, as indicated at 23.

The containers 11, which are adapted to contain mercury, or othersuitable liquid, are balanced upon the pivot 13, their positiondetermining the degree of opening of the valve 19. Air or other fluidpassing through the conduit 10 will be permitted to flow through thesaid conduit and the amount determined by the position of the. valve. Anexcem quantity of air or liquid will cause an unbalanced'pressure incontainers 11, due to the difference in static pressure in the pipe 15and velocity pressure plus stat1c pressure against the open end of theplpe 18. This difference in pressure will cause a flow from onecontainer to the other until the containers have tilted an amountnecessary to operate the valve 19, until flow has been reduced to theamount for which the regulator has been adjusted, the said adjustmentbeing made by any suitable means. The invention is susceptible ofvarious changes in its form, proportions and minor details ofconstruction and the right is herein reserved to make such changes asproperly fall within the scope of the appended claim.

Having described the invention, whatis claimed is:

A regulator comprising a conduit, a valve located within the conduit andcontrolling the passage therethrough, a member pivotally mounted abovethe conduit, said member comprising spaced liquid containers and a pipeconnecting the containers, a static pressure pipe establishingcommunication between one of the containers and the conduit, a tubehaving one end extending Within the conduit and the other end connectingwith the other container, an arm connected to the valve and a linkhaving one end pivotally connected to the valve and its oppo containerconnecting pipe upon one side of the pivotal mounting of the latter,whereby movement of the containers will regulate the position of the ENNIS NEVINS.
